Improvement in impalpable soaps



JOHN P. BRYAN, or cANToN, OHIO, ASSIGNOR-TO'THE CENTRAL SOAP COMPANY, OFSAME PLACE.

IMPROVEMENT IN IMPALPABLE SOAPS.

Specification forming part of Letters Patent No. 163,571, dated May 25,1875; application filed March 29, 1875.

To all whom it mayconcern:

Be it known that I, JOHN P. BRYAN, of Canton, in the county of Stark andState of Ohio,

have invented certain new and useful Improvements in Soap; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable othcess in the preparation oftoilet and othersoaps; and consists inthe steps, hereinafter specifiedand claimed, for reducing said soap to the form of an impalpable powder.

In carrying out my process the steps are substantially as follows: Itake cocoa-oil and caustic lye, in suitable proportions, and saponifythem. While in a fluid state I add twenty-five per cent, more or less,of silex, or some equivalent thereof. I also take tallow, or somekindred substance, and caustic lye, insuitable proportions, and saponifythem, and while in a fluid state add twenty-five per cent., more orless, of silex, or an y equivalent thereof. The ofiice of the silex willhereinafter more fully and at large appear. I then take one part of theformer to three parts of the latter, mix them, and reduce to a powder bycutting, drying, and pulverizing them. The mass is pulverized betweenmillstones, or in any other suitable way, whereby it is thoroughlyground and reduced. It is then bolted through silk bolting-cloths. Thedrying is preferably eft fected by hot air. ,After the soap has thusbeen properly prepared by mixing, drying,-

grinding, and bolting, as above stated, I then perfume it, if desired,by casting into it a spray of essential oils, or any perfumingsubstance.

The object in adding the silex is to make the soap pulverize easily, andto render it dry. It serves also to keep it dry. Moreover, it has adetersive quality. i

I do not, however, limit myself to the employment of silica, as someother ingredient may perform a like function of enabling me to pulverizeand reduce the mass to a dry impalpable powder.

.Thc'product of my invention is a light, dry, and impalpablc powder,that is readily sifted through a perforated surface-as, for instance, apepper-box, or the like-and it will not cake or glue itself together.

What I claim as my invention is The process, substantially as hereindescribed, consisting in mixing with any saponaceous compound suchsubstance or material as shall render the mass readily pulverizable,then drying and grinding the mass, whereby it is reduced to animpalpable powder, substantially as and for the purposes described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. 1
